The invention provides a sprocket carrier capable of reducing volume in a state of being detached from a multi-stage rear sprocket assembly. A sprocket carrier (55) is used in a multi-stage rear sprocket assembly (27) comprising a plurality of joining sprockets (31) and at least one separating sprocket (33). The sprocket carrier (55) is provided with a base body (61). The base body (61) is configured to deform between a flat state and an engaged state. In the flat state, the base body (61) is flat. In the engaged state, in a state where the sprocket carrier (55) is engaged with the multi-stage rear sprocket assembly (27), the base body (61) deforms at least in the axial direction of the multi-stage rear sprocket assembly (27) with respect to the rotational center axis (X).
本发明提供一种能够在从多级后链轮组件被卸下的状态下减小体积的链轮架。链轮架(55)被用于包括多个连结链轮(31)以及至少一个分离链轮(33)的多级后链轮组件(27)中。链轮架(55)具备基体(61)。基体(61)构成为在平坦状态及卡合状态之间进行变形。在平坦状态时,基体(61)是平坦的。在卡合状态时,在链轮架(55)与多级后链轮组件(27)卡合的状态下,基体(61)沿多级后链轮组件(27)的关于旋转中心轴心线(X)的至少轴向进行变形。
